C# Global Variables Accessing

I have created a class as the following it has one global variable.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace LankaLab
{
    class dbConnect
    {

        public String strSuperPatID;

        public String StrSuperPatID
        {
            get { return strSuperPatID; }
            set { strSuperPatID = value; }
        }

                     
         }
}

Now I have created another class and I have created an instance of the dbConnect class.

 public partial class frmFulBldCuntDet : Form
{

  private dbConnect dbConn = new dbConnect();

 }

Now I want to set values to the global variable in the dbConnect class from the frmBldCuntDet class. I already created the getter() & setter() methods. But now I want to add values to the strSuperPatID from the frmBldCuntDet and display it from another class ( haven't created yet). All I need is to use getter() & setter(0 methods.

Thank You!

Moved to question from OP "solution" - OriginalGriff

frmBldCuntDet class has the following variables and those use to generate a automatic patient id.

 Class - 01
            
            public partial class frmFulBldCuntDet : Form
    {
            private dbConnect dbConn = new dbConnect();

            private String strID;
            private String strPatID;

            private int intYear;
            private String strYear;

            private int intMonth;
            private String strMonth;

         private void btnPrint_Click(object sender, EventArgs e)
        {
            intYear = DateTime.Now.Year;
            strYear = intYear.ToString();
            intMonth = DateTime.Now.Month;
            strID = cmbPatID.Text;

//MyMethod() in use.
            MyMethod();

      frmHBAIC HbIAC01 = new frmHBAIC();

      HbIAC01.show(); 

       }
         /* This MyMethod will pass the value of strPatID to the global variable StrSuperPatID */
           private string MyMethod() {

            return(dbConn.StrSuperPatID = strPatID);
        
        }

    }

 Class - 02

  public partial class frmHBAIC : Form
    {

     private dbConnect dbConn = new dbConnect();

   /* When the button1 is clicked I want to display the value of StrSuperPatID (global variable) in a messagebox.*/
   // I tried this as the follwoing but it didn't happen!
      private void button1_Click(object sender, EventArgs e)
        {
          MessageBox.show(dbConn.StrSuperPatID);  
        }

    }

  Class - 03 - This class includes the global variables and getter & setter metohds of its'.

  class dbConnect
    {

        public String strSuperPatID;

        public String StrSuperPatID
        {
            get { return strSuperPatID; }
            set { strSuperPatID = value; }
        }

                     
         }

I cannot find the problem yet that preventing passing the values to the global variable.

Hope that you will help me

Thank You!
